can someone help me make a class UML diagram for my code

/********************************************************************************* * (Game: hangman) Write a hangman game that randomly generates a word and * * prompts the user to guess one letter at a time, as shown in the sample run. * * Each letter in the word is displayed as an asterisk. When the user makes a * * correct guess, the actual letter is then displayed. When the user finishes a * * word, display the number of misses and ask the user whether to continue to * * play with another word. Declare an array to store words, as follows: * *********************************************************************************/ import java.util.Scanner; public class Exercise_07_35 { /* Main method */ public static void main(String[] args) { Scanner input = new Scanner(System.in); String play; // 'y' or 'n' do { // Generate a random word  char[] word = getWord(); // Display each letter in the word as an asterisk. char[] asterisks = new char[word.length]; fillAsterisks(asterisks); int missed = 0; // number of wrong guesses do { // Prompt the user to guess one letter char guess = getGuess(asterisks); // Check if is letter is correct if (!isCorrectGuess(word, asterisks, guess)) missed++; } while (!isWordFinish(asterisks)); // Print results print(word, missed); // Ask the user whether to continue to play with another word System.out.println("Do you want to guess another word?
